Prestressed steel wire of sizing thread rolling

Abstract

The invention provides a prestressed steel wire of sizing thread rolling. The prestressed steel wire is prepared from the following ingredients by weight percent: 0.05 to 0.1 percent of carbon, 0.8 to 2 percent of manganese, 0.1 to 0.8 percent of silicon, 3 to 8 percent of nickel, 0.0004 to 0.01 percent of boron, 0.05 to 1 percent of chromium, 0.3 percent or less of aluminum, 0.02 percent or less of phosphorus, 0.01 percent or less of sulfur, 0.8 percent or less of copper and the balance of Fe and impurity element. The prestressed steel wire has the beneficial effects that the steel wire produced by virtue of the scheme is good in flexibility and high in strength, and the performance indexes under the strict condition can be satisfied.

Description

technical field [0001] The invention belongs to the field of iron and steel, and in particular relates to a prestressed steel wire of fixed-length wire rolling. Background technique [0002] Prestressed steel wire is a kind of steel wire specially used in prestressed concrete structure or prestressed steel structure, and fixed-length rolling wire is based on ordinary prestressed steel wire with external thread at both ends, which is convenient for use. But the performance of the current steel wire is not ideal, the strength is not high, and it cannot fully meet the demand. Contents of the invention [0003] The present invention provides a prestressed steel wire for rolling to a fixed length. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a prestressed steel wire for rolling to a fixed length, which contains: 0.05% to 0.1% of carbon, 0.8% to 2% of manganese, 0.1% to 0.8% of silicon, 3% to 8% ...
